LOCATION YELLOWDOG MIEstablished Series
TAXONOMIC CLASS: Sandy-skeletal, mixed, frigid Typic Udorthents
TYPICAL PEDON: Yellowdog very channery sand - on a 2 percent slope in a forested area. (Colors are for moist unless otherwise stated.)
Oa--0 to 2 inches; black (10YR 2/1) well decomposed leaf litter; moderate very fine granular structure; very friable; many very fine to coarse roots; very strongly acid; abrupt smooth boundary. (0 to 3 inches thick)
Bw1--2 to 22 inches; reddish brown (5YR 4/4) very channery sand; weak very fine subangular blocky structure; very friable; many very fine to coarse roots; about 55 percent sandstone channers; very strongly acid; gradual wavy boundary.
Bw2--22 to 32 inches; reddish brown (5YR 5/4) very channery sand; weak very fine subangular blocky structure; very friable; common very fine to medium roots; about 55 percent sandstone channers; moderately acid; abrupt wavy boundary. (combined thickness of the Bw horizon ranges from 11 to 30 inches)
2R--32 inches; dusky red (2.5YR 3/2) sandstone bedrock; hard bedrock contains fractures from 2 to 10 mm thick that range from 1 to 5 feet apart; common very fine roots in bedrock fractures.
TYPE LOCATION: Marquette County, Michigan; about six miles east of Big Bay, 2,475 feet south and 2,475 feet west of the northeast corner of sec. 20, T. 51 N., R. 26 W.
RANGE IN CHARACTERISTICS: Solum thickness and depth to bedrock ranges from 20 to 40 inches. The reaction ranges from very strongly acid to moderately acid. The content of rock fragments, which consists mainly of sandstone channers ranges from 35 to 75 percent throughout the pedon.
Some pedons have an A horizon with hue of 10YR and value of 2 or 3, and chroma of 1. It is the very channery analogues of sand or loamy sand.
The Bw horizons have hue of 2.5YR or 5YR, value of 4 or 5 and chroma of 4. They are very channery sand or extremely channery sand.
COMPETING SERIES: These are the Emmert and Stonelake series. None of these soils have a lithic contact within 60 inches.
GEOGRAPHIC SETTING: Yellowdog soils are on sandstone benches along Lake Superior. Slope gradients range from 0 to 6 percent. Mean annual precipitation ranges from 30 to 33 inches and mean annual temperature is about 40 to 42 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Munising, Deerton, Burt, and Skandia (proposed) soils. The very deep, moderately well drained Munising soils are in higher landscape positions. The moderately deep, excessively drained Deerton soils occur on similar positions in the landscape. Areas of poorly drained Burt soils and very poorly drained Skandia soils are in lower landscape positions and depressions. In some places the poorly drained Burt soils are in a complex pattern with Yellowdog soils.
DRAINAGE AND PERMEABILITY: Excessively drained. Surface runoff is slow. Permeability is very rapid in the sandy mineral material and slow or moderately slow in the sandstone bedrock. Internal drainage is impeded by the bedrock.
USE AND VEGETATION: Used almost entirely for woodland. Vegetation is mixed northern hardwood forest dominantly of sugar maple.
DISTRIBUTION AND EXTENT: Central Upper Peninsula of Michigan. The series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: St. Paul, Minnesota.
SERIES ESTABLISHED: Marquette County, Michigan, 1998. Source of name is a river in the county.
REMARKS: Diagnostic horizons and features recognized in this pedon are: lithic contact - the boundary with hard bedrockat about 32 inches.
